る、組成物に関する。Conventionally, a recording substrate containing an image formed by toner is passed through a fixing chamber in an atmosphere saturated with a gaseous fixing agent at a temperature of 50 to 100 ° C. Depending on the fixing agent used, the toner is quickly fixed to the recording substrate, enabling high speed printing or copying. The recording substrate containing the toner to be fixed is usually contacted with the fixing agent for a period of 0.5 to 3 seconds. Toners that can be fixed by the method of the present invention are especially suitable in Kirk-Othmer, Encyclopedia of Chemic.
al Technology, 4th Ed., Vol. 9, pages 270-271, as described in the section relating to electrophotography, for example based on a thermoplastic resin colored or pigmented with carbon black, free-flowing. It consists of fine grains. The method of the invention applies in particular to the fixing of powder toners which consist essentially of a polymer matrix, for example a matrix based on polystyrene or polyester, and a pigment. The fixing method of the present invention in which the fixing agent contains a co-solvent is particularly suitable for fixing a toner containing a polyester-based polymer matrix. The method of the present invention allows fixing of toner to a large number of recording substrates, especially paper, transparent sheets made from synthetic polymeric materials, and natural or synthetic fibers. The fixatives used in the method of the present invention generally do not adversely affect the recording substrates commonly used in printing or copying processes using powder toners. The present invention also relates to a composition containing a C3 to C6 fluorohydrocarbon and a C2 to C8 ester and corresponding to a fixing agent preferably used in the fixing method of the present invention.
